FIELD OF THE INVENTION

The present invention relates to an adeno-associated virus (AAV) vector comprising a variant capsid polypeptide more cationic than a non-variant parent capsid polypeptide and/or another variant capsid polypeptide providing an AAV vector with increased packaging capacity compared to that of a non-variant peptide capsid.

BACKGROUND OF THE INVENTION

Genetic disorders caused by absence of or a defect in a desirable gene (loss of function) or expression of an undesirable or defective gene or (gain of function) lead to a variety of diseases. One example of a loss of function genetic disorder is hemophilia, an inherited bleeding disorder caused by deficiency in either coagulation factor VIII (FVIII, hemophilia A) or factor IX (FIX, hemophilia B). One example of a gain of function genetic disorder is Huntington's disease, a disease caused by a pathologic “HTT” gene (encodes the huntingtin protein) encoding a mutated protein accumulating within and leading to gradual destruction of neurons, particularly in the basal ganglia and the cerebral cortex.

Current treatment for hemophilia consists of intravenous administration of recombinant clotting factor either on demand, upon occurrence of a bleeding event, or prophylactically, preventing a bleeding occurrence (for example, prior to surgical procedures). However, this therapeutic approach has several drawbacks such as the need for repeated infusions, the cost of the treatment, the risk of developing anti-therapeutic factor immune responses, and the risk of potentially fatal bleedings. These limitations prompted the development of gene-based therapies for hemophilia. Hemophilia is ideal for gene transfer based therapy as 1) the therapeutic window is very wide, as levels just above 1% of normal already can result in a change in phenotype from severe to moderate, and levels of 100% are not associated to any side effects; 2) tissue specific expression of the therapeutic transgene is not strictly required; and 3) there is considerable experience in measuring the endpoints of therapeutic efficacy. Furthermore, liver expression of clotting factor was demonstrated to induce immunological tolerance to the clotting factor itself, reducing the likelihood of potentially harmful immune responses against clotting factor.

At present, adeno-associated virus (AAV) vectors are recognized as the gene transfer vectors of choice for therapeutic applications since they have the best safety and efficacy profile for the delivery of genes in vivo. Of the AAV serotypes isolated so far, AAV2 and AAV8 have been used to target the liver of humans affected by severe hemophilia B. Both vectors worked efficiently and, in the case of AAV8, long-term expression of the therapeutic transgene was documented. Recent data from humans showed that targeting the liver with an AAV vector achieves long-term expression of the FIX transgene at therapeutic levels.

Adeno-associated virus (AAV), a member of the Parvovirus family, is a small nonenveloped, icosahedral virus with single-stranded linear DNA genomes of 4.7 kilobases (kb) to 6 kb. AAV is assigned to the genus, Dependovirus, because the virus was discovered as a contaminant in purified adenovirus stocks. AAV's life cycle includes a latent phase during which AAV genomes, after infection, are site specifically integrated into host chromosomes and an infectious phase during which, following either adenovirus or herpes simplex virus infection, the integrated genomes are subsequently rescued, replicated, and packaged into infectious viruses. The properties of non-pathogenicity, broad host range of infectivity, including non-dividing cells, and potential site-specific chromosomal integration make AAV an attractive tool for gene transfer.

However, the limited packaging capacity of adeno-associated virus (AAV) precludes the design of AAV based vectors for the treatment of diseases associated with larger genes. Autonomous parvoviruses, such as minute virus of mice and B19, while identical in size (25 nm) with AAV, are known to package larger genomes of 5.1 and 5.6 kb, respectively, compared to AAV genomes of 4.7 kb (see, for example, Grieger, J.C. and Samulski, R. J., (2005) Amer. Soc. for Microbiology, 79(15):9933-9944). One primary difference is the fact that wild-type (wt) AAV utilizes three capsid subunits instead of two to form the virion shell. A variety of published U.S. applications describe AAV vectors and virions, including U.S. Publication Nos. 2015/0176027, 2015/0023924, 2014/0348794, 2014/0242031, and 2012/0164106; all of which are incorporated by reference herein in their entireties.

There remains, therefore, a need in the art for AAV vectors with increased packaging capacity. The present invention meets this need by providing AAV vectors and AAV virions with enhanced increased packaging capacity.

BRIEF SUMMARY OF THE INVENTION

The present invention provides an adeno-associated virus (AAV) vector comprising a nucleic acid sequence encoding a variant capsid polypeptide. The variant capsid polypeptide is more cationic than an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide. The vector encoding the variant capsid polypeptide is capable of comprising a longer nucleic acid insert than a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the longer nucleic acid insert is at least about 5% longer, e.g., at least about 10% longer, e.g., at least about 15% longer, e.g., at least about 20% longer, e.g., at least about 25% longer than an otherwise identical nucleic acid insert packageable in a wild-type adenovirus capsid.

In some embodiments, the longer nucleic acid insert is at least about 100, at least about 300, at least about 500, at least about 700, at least about 1000, at least about 1200, or at least about 1500 nucleic acids longer than an otherwise identical nucleic acid insert packageable in a wild-type adenovirus capsid. In some embodiments, the longer nucleic acid insert is at least about 600 nucleic acids longer. In some embodiments, the longer nucleic acid insert is at least about 900 nucleic acids longer.

In some embodiments, the variant capsid polypeptide comprises at least 1 additional positive amino acid substitution compared to an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide comprises at least 1, 2, 3, 4, 5, 6 or 7 positive amino acid substitution compared to an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide comprises at least a +1 lumenal charge compared to an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide comprises at least a +1, +2, +3, +4, +5, +6, +7 lumenal charge as compared to an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, an increase in the positive lumenal charge of the variant capsid polypeptide results in an increase in the length of the longer nucleic acid said AAV vector is capable of comprising.

In some embodiments, the vector is at least about 5000 nucleic acids, e.g., at least about 5500 nucleic acids in total length.

In some embodiments, the vector encoding said variant capsid polypeptide is packaged similarly to a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, e.g., similarly includes for example, variant capsid polypeptides and non-variant parent capsid polypeptides and/or another variant capsid polypeptides packaged into functional AAV virions where the packaging and/or virion function is substantially the same between the variant capsid polypeptide and non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid exhibits at least 100%, at least 99%, at least 95%, at least 90%, at least 85%, at least 80%, at least 75% or at least 70% of the packaging activity and/or function of a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the vector encoding said variant capsid polypeptide transduces cells in vivo similarly to a vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, e.g., similarly includes for example, variant capsid polypeptides and non-variant parent capsid polypeptides and/or another variant capsid polypeptides both function to transduce cells in vivo in substantially the same manner. In some embodiments, similar transduction indicates the variant capsid polypeptide exhibits at least 100%, at least 99%, at least 95%, at least 90%, at least 85%, at least 80%, at least 75% or at least 70% of the transducing activity of a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the vector encoding said variant capsid polypeptide transduces cells in vitro similarly to a vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, e.g., similarly includes for example variant capsid polypeptides and non-variant parent capsid polypeptides and/or another variant capsid polypeptides function to transduce cells in vitro in substantially the same manner. In some embodiments, similar transduction indicates the variant capsid polypeptide exhibits at least 100%, at least 99%, at least 95%, at least 90%, at least 85%, at least 80%, at least 75% or at least 70% of the transducing activity of a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the vector encoding said variant capsid polypeptide results in transgene expression similarly to a vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, e.g., similarly includes for example variant capsid polypeptide and non-variant parent capsid polypeptide vectors function to allow for transgene expression level in substantially the same manner. In some embodiments, similar transgene expression indicates that the variant capsid exhibits at least 100%, at least 99%, at least 95%, at least 90%, at least 85%, at least 80%, at least 75% or at least 70% of the transgene expression level of a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the longer nucleic acid insert comprises a nucleic acid sequence selected from the group consisting of a non-coding RNA, coding sequence, an expression cassette, a multi-expression cassette, a sequence for homologous recombination, and a therapeutic expression cassette.

In some embodiments, the expression cassette is a CRISPR/CAS expression system.

DETAILED DESCRIPTION OF THE INVENTION Introduction

There remains a need in the art for gene therapy vectors capable of expressing longer nucleic acids (longer transgenes), as some polypeptides such as Factor VIII are encoded by nucleic acids too large for standard AAV vectors. The present invention meets this need and provides AAV vectors encoding variant capsid polypeptides, allowing the vectors of the invention to comprise longer nucleic acid sequences than vectors encoding non-variant parent capsid polypeptides and/or another variant capsid polypeptides. The variant capsid polypeptides of the present invention are more cationic than the otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

DETAILED DESCRIPTION

In various embodiments, the present invention provides adeno-associated virus (AAV) vectors comprising a nucleic acid sequence coding for a variant capsid polypeptide, wherein the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, and wherein said vector comprising said variant capsid polypeptide is capable of comprising a longer nucleic acid insert as compared to a vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments the AAV vector is referred to as a recombinant AAV or rAAV vector.

In some embodiments, the present invention provides adeno-associated virus (AAV) vectors comprising: a) a variant AAV capsid protein, wherein the variant AAV capsid polypeptide comprises at least one amino acid difference (e.g., amino acid substitution, amino acid insertion, amino acid deletion) relative to a substantially identical non-variant parent AAV capsid protein, and where the variant capsid protein is more cationic than a non-variant parent AAV capsid protein and wherein said AAV vector comprising said variant capsid polypeptide is capable of comprising a longer nucleic acid insert as compared to an AAV vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the AAV capsid polypeptide does not comprise an amino acid sequence present in a naturally occurring AAV capsid polypeptide.

The term covers all subtypes and both naturally occurring and recombinant forms, except where required otherwise. The abbreviation “rAAV” refers to recombinant adeno-associated virus, also referred to as a recombinant AAV vector (or “rAAV vector”).

Definitions

The term “AAV” includes AAV type 1 (AAV1), AAV type 2 (AAV2), AAV type 3 (AAV3), AAV type 4 (AAV4), AAV type 5 (AAV5), AAV type 6 (AAV6), AAV type 7 (AAV7), AAV type 8 (AAV8), AAV type 9 (AAV9), avian AAV, bovine AAV, canine AAV, equine AAV, primate AAV, non-primate AAV, and ovine AAV. “Primate AAV” refers to AAV capable of infecting primates, “non-primate AAV” refers to AAV capable of infecting non-primate mammals, “bovine AAV” refers to AAV capable of infecting bovine mammals, etc.

An “AAV vector” as used herein refers to an AAV vector nucleic acid sequence encoding for a variant capsid polypeptide (i.e., the AAV vector comprises a nucleic acid sequence encoding for a variant capsid polypeptide), wherein the variant capsid polypeptide is more cationic than a substantially identical a non-variant parent capsid polypeptide and/or another variant capsid polypeptide, and wherein said vector comprising said variant capsid polypeptide is capable of comprising a longer nucleic acid insert as compared to a vector comprising a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. The AAV vectors can further comprise a heterologous nucleic acid sequence not of AAV origin (i.e., a nucleic heterologous to AAV), as part of the longer nucleic acid insert. This heterologous nucleic acid sequence typically comprises a sequence of interest for the genetic transformation of a cell. In general, the heterologous nucleic acid sequence is flanked by at least one, and generally by two AAV inverted terminal repeat sequences (ITRs).

The phrase “non-variant parent capsid polypeptide” includes any naturally occurring AAV capsid polypeptide and/or any AAV wild-type capsid polypeptide. In some embodiments, the non-variant parent capsid polypeptide includes AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, and/or AAV8 capsid polypeptides. In some embodiments, the non-variant parent capsid polypeptide is selected from the group consisting of SEQ ID NO: 96 (wild-type or parental DJ) or SEQ ID NO: 97 (wild-type or parental AAV8).

The phrase “another variant capsid polypeptide” refers to any variant capsid polypeptide disclosed and/or described herein, including those listed by SEQ ID NO:. In some embodiments, the another variant capsid polypeptide is selected from the group consisting of: AAV-DJ V24 (SEQ ID NO: 12); AAV-DJ V22 (SEQ ID NO: 10); AAV-DJ V26 (SEQ ID NO: 13); AAV-DJ V12 (SEQ ID NO: 5); AAV8-12 (SEQ ID NO: 92), AAV8-24 (SEQ ID NO: 94) and AAV8-26 (SEQ ID NO: 95). In some embodiments, the another variant capsid polypeptide is selected from the group consisting of : AAV-DJ V24 (SEQ ID NO: 12); AAV-DJ V26 (SEQ ID NO: 13); and AAV-DJ V12 (SEQ ID NO: 5). In some embodiments, the another variant capsid polypeptide is selected from the group consisting of : AAV-DJ V26 Sequence (SEQ ID NO: 13) and AAV-DJ V12 Sequence (SEQ ID NO: 5). In some embodiments, the another variant capsid polypeptide is selected from the group consisting of: AAV-DJ V12 Sequence (SEQ ID NO: 5). In some embodiments, the another variant capsid polypeptide is selected from the group consisting of: AAV8-12 (SEQ ID NO: 92).

The phrase “non-variant capsid parental lumenal charge” refers to the lumenal charge in the non-variant parent capsid polypeptide. In some cases, this can be defined based on the definition of the lumen exposure. Percent lumen exposure is calculated as the solvent excluded surface of a given amino acid in the structure divided by the same measurement in the reference state G-X-G tripeptide. Specifically, it is the relative exposure of a given amino acid, because it normalizes the exposure based upon the amino acid side chain size (for example, tryptophan is 3-times larger than glycine) and in a reference state where the side chain is completely exposed. Calculations can be done using the program Chimera. (See, e.g., Transient protein-protein interface prediction: datasets, features, algorithms, and the RAD-T predictor. Bendell C J, Liu S, Aumentado-Armstrong T, Istrate B, Cernek P T, Khan S, Picioreanu S, Zhao M, Murgita R A. BMC Bioinformatics. 2014 Mar 24;15:82; as well as the World Wide Web at cgl.ucsfeduichimera/docs/UsersGuide/surfnorm.html.) Percent lumen exposure can be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%.

By the term “substantially identical” in the context of variant capsid polypeptides and non-variant parent capsid polypeptides include sequences with 1 or amino acid changes. In some embodiments, these changes do not affect the function of the capsid polypeptide. In some embodiments, substantially identical include variant capsid polypeptides about 99%, about 98%, about 97%, about 96%, about 95%, about 94%, about 93%, about 92%, about 91%, or about 90% identical to a non-variant parent capsid polypeptide. In some embodiments, the variant capsid polypeptide can be substantially identical to a non-variant parent capsid polypeptide over a subregion of the variant capsid polypeptide, such as over about 25%., about 50%, about 75%, or about 90% of the total polypeptide sequence length.

An “AAV virion” or “AAV virus” or “AAV viral particle” or “AAV vector particle” refers to a viral particle composed of at least one AAV capsid polypeptide (including both variant capsid polypeptides and non-variant parent capsid polypeptides) and an encapsidated polynucleotide AAV vector. If the particle comprises a heterologous nucleic acid (i.e. a polynucleotide other than a wild-type AAV genome, such as a transgene to be delivered to a mammalian cell), it can be referred to as an “AAV vector particle” or simply an “AAV vector”. Thus, production of AAV virion or AAV particle necessarily includes production of AAV vector as such a vector is contained within an AAV virion or AAV particle.

“Packaging” refers to a series of intracellular events resulting in the assembly and encapsidation of an AAV virion or AAV particle.

AAV “rep” and “cap” genes refer to polynucleotide sequences encoding replication and encapsidation proteins of adeno-associated virus. AAV rep (replication) and capsid (capsid) are referred to herein as AAV “packaging genes.”

A “helper virus” for AAV refers to a virus allowing AAV (e.g. wild-type AAV) to be replicated and packaged by a mammalian cell. A variety of such helper viruses for AAV are known in the art, including adenoviruses, herpesviruses and poxviruses such as vaccinia. The adenoviruses encompass a number of different subgroups, although Adenovirus type 5 of subgroup C is most commonly used as a helper virus. Numerous adenoviruses of human, non-human mammalian and avian origin are known and available from depositories such as the ATCC. Viruses of the herpes family include, for example, herpes simplex viruses (HSV) and Epstein-Barr viruses (EBV), as well as cytomegaloviruses (CMV) and pseudorabies viruses (PRV); which are also available from depositories such as ATCC.

“Helper virus function(s)” refers to function(s) encoded in a helper virus genome allowing AAV replication and packaging (in conjunction with other requirements for replication and packaging described herein). As described herein, “helper virus function” may be provided in a number of ways, including by providing helper virus or providing, for example, polynucleotide sequences encoding the requisite function(s) to a producer cell in trans.

An “infectious” virion, virus or viral particle is one comprising a polynucleotide component deliverable into a cell tropic for the viral species. The term does not necessarily imply any replication capacity of the virus. As used herein, an “infectious” virus or viral particle is one that upon accessing a target cell, can infect a target cell, and can express a heterologous nucleic acid in a target cell. Thus, “infectivity” refers to the ability of a viral particle to access a target cell, infect a target cell, and express a heterologous nucleic acid in a target cell. Infectivity can refer to in vitro infectivity or in vivo infectivity. Assays for counting infectious viral particles are described elsewhere in this disclosure and in the art. Viral infectivity can be expressed as the ratio of infectious viral particles to total viral particles. Total viral particles can be expressed as the number of viral genome copies. The ability of a viral particle to express a heterologous nucleic acid in a cell can be referred to as “transduction.” The ability of a viral particle to express a heterologous nucleic acid in a cell can be assayed using a number of techniques, including assessment of a marker gene, such as a green fluorescent protein (GFP) assay (e.g., where the virus comprises a nucleotide sequence encoding GFP), where GFP is produced in a cell infected with the viral particle and is detected and/or measured; or the measurement of a produced protein, for example by an enzyme-linked immunosorbent assay (ELISA).

A “replication-competent” virion or virus (e.g. a replication-competent AAV) refers to an infectious phenotypically wild-type virus, and is replicable in an infected cell (i.e. in the presence of a helper virus or helper virus functions). In the case of AAV, replication competence generally requires the presence of functional AAV packaging genes. In some embodiments, AAV vectors, as described herein, lack of one or more AAV packaging genes and are replication-incompetent in mammalian cells (especially in human cells) . In some embodiments, AAV vectors lack any AAV packaging gene sequences, minimizing the possibility of generating replication competent AAV by recombination between AAV packaging genes and an incoming AAV vector. In many embodiments, AAV vector preparations as described herein are those containing few if any replication competent AAV (rcAAV, also referred to as RCA) (e.g., less than about 1 rcAAV per 10² AAV particles, less than about 1 rcAAV per 10⁴ AAV particles, less than about 1 rcAAV per 10⁸ AAV particles, less than about 1 rcAAV per 10¹² AAV particles, or no rcAAV).

The terms “polynucleotide” and “nucleic acid” are used interchangeably herein to refer to all forms of nucleic acid, oligonucleotides, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Polynucleotides include genomic DNA, cDNA and antisense DNA, and spliced or unspliced mRNA, rRNA, tRNA, lncRNA, RNA antagomirs, and inhibitory DNA or RNA (RNAi, e.g., small or short hairpin (sh)RNA, microRNA (miRNA), aptamers, small or short interfering (si)RNA, trans-splicing RNA, or antisense RNA). Polynucleotides also include non-coding RNA, which include for example, but are not limited to, RNAi, miRNAs, lncRNAs, RNA antagomirs, aptamers, and any other non-coding RNAs known to those of skill in the art. Polynucleotides include naturally occurring, synthetic, and intentionally altered or modified polynucleotides as well as analogues and derivatives. The term “polynucleotide” also refers to a polymeric form of nucleotides of any length, including deoxyribonucleotides or ribonucleotides, or analogs thereof, and is synonymous with nucleic acid sequence. A polynucleotide may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs, and may be interrupted by non-nucleotide components. If present, modifications to the nucleotide structure may be imparted before or after assembly of the polymer. The term polynucleotide, as used herein, refers interchangeably to double- and single-stranded molecules. Unless otherwise specified or required, any embodiment as described herein encompassing a polynucleotide encompasses both the double-stranded form and each of two complementary single-stranded forms known or predicted to make up the double-stranded form. Polynucleotides can be single, double, or triplex, linear or circular, and can be of any length. In discussing polynucleotides, a sequence or structure of a particular polynucleotide may be described herein according to the convention of providing the sequence in the 5′ to 3′ direction.

A “gene” refers to a polynucleotide containing at least one open reading frame capable of encoding a particular protein or polypeptide after being transcribed and translated.

A “small interfering” or “short interfering RNA” or siRNA is a RNA duplex of nucleotides targeted to a gene interest (a “target gene”). An “RNA duplex” refers to the structure formed by the complementary pairing between two regions of a RNA molecule. siRNA is “targeted” to a gene and the nucleotide sequence of the duplex portion of the siRNA is complementary to a nucleotide sequence of the targeted gene. In some embodiments, the length of the duplex of siRNAs is less than 30 nucleotides. In some embodiments, the duplex can be 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11 or 10 nucleotides in length. In some embodiments, the length of the duplex is 19-25 nucleotides in length. The RNA duplex portion of the siRNA can be part of a hairpin structure. In addition to the duplex portion, the hairpin structure may contain a loop portion positioned between the two sequences forming the duplex. The loop can vary in length. In some embodiments the loop is 5, 6, 7, 8, 9, 10, 11, 12 or 13 nucleotides in length. The hairpin structure can also contain 3′ or 5′ overhang portions. In some embodiments, the overhang is a 3′ or a 5′ overhang 0, 1, 2, 3, 4 or 5 nucleotides in length.

As used herein, the term “microRNA” refers to any type of interfering RNAs, including but not limited to, endogenous microRNAs and artificial microRNAs (e.g., synthetic miRNAs). Endogenous microRNAs are small RNAs naturally encoded in the genome capable of modulating the productive utilization of mRNA. An artificial microRNA can be any type of RNA sequence, other than endogenous microRNA, capable of modulating the activity of an mRNA. A microRNA sequence can be an RNA molecule composed of any one or more of these sequences. MicroRNA (or “miRNA”) sequences have been described in publications such as Lim, et al., 2003, Genes & Development, 17, 991-1008, Lim et al., 2003, Science, 299, 1540, Lee and Ambrose, 2001, Science, 294, 862, Lau et al., 2001, Science 294, 858-861, Lagos-Quintana et al., 2002, Current Biology, 12, 735-739, Lagos-Quintana et al., 2001, Science, 294, 853-857, and Lagos-Quintana et al., 2003, RNA, 9, 175-179. Examples of microRNAs include any RNA fragment of a larger RNA or is a miRNA, siRNA, stRNA, sncRNA, tncRNA, snoRNA, smRNA, shRNA, snRNA, or other small non-coding RNA. See, e.g., U.S. Patent Applications 20050272923, 20050266552, 20050142581, and 20050075492. A “microRNA precursor” (or “pre-miRNA”) refers to a nucleic acid having a stem-loop structure with a microRNA sequence incorporated therein. A “mature microRNA” (or “mature miRNA”) includes a microRNA cleaved from a microRNA precursor (a “pre-miRNA”), or synthesized (e.g., synthesized in a laboratory by cell-free synthesis), and has a length of from about 19 nucleotides to about 27 nucleotides, e.g., a mature microRNA can have a length of 19 nt, 20 nt, 21 nt, 22 nt, 23 nt, 24 nt, 25 nt, 26 nt, or 27 nt. A mature microRNA can bind to a target mRNA and inhibit translation of the target mRNA.

“Recombinant,” as applied to a polynucleotide means the polynucleotide is the product of various combinations of cloning, restriction or ligation steps, and other procedures resulting in a construct distinct and/or different from a polynucleotide found in nature. A recombinant virus is a viral particle comprising a recombinant polynucleotide. The terms respectively include replicates of the original polynucleotide construct and progeny of the original virus construct.

A “control element” or “control sequence” is a nucleotide sequence involved in an interaction of molecules contributing to the functional regulation of a polynucleotide, including replication, duplication, transcription, splicing, translation, or degradation of the polynucleotide. The regulation may affect the frequency, speed, or specificity of the process, and may be enhancing or inhibitory in nature. Control elements known in the art include, for example, transcriptional regulatory sequences such as promoters and enhancers. A promoter is a DNA region capable under certain conditions of binding RNA polymerase and initiating transcription of a coding region usually located downstream (in the 3′ direction) from the promoter.

“Operatively linked” or “operably linked” refers to a juxtaposition of genetic elements, wherein the elements are in a relationship permitting them to operate in the expected manner. For instance, a promoter is operatively linked to a coding region if the promoter helps initiate transcription of the coding sequence. There may be intervening residues between the promoter and coding region so long as this functional relationship is maintained.

“Heterologous” means derived from a genotypically distinct entity from the rest of the entity to it is being compared too. For example, a polynucleotide introduced by genetic engineering techniques into a plasmid or vector derived from a different species is a heterologous polynucleotide. A promoter removed from its native coding sequence and operatively linked to a coding sequence it is not naturally found linked to a heterologous promoter. For example, an AAV including a heterologous nucleic acid encoding a heterologous gene product is an AAV including a nucleic acid not normally included in a naturally-occurring, wild-type AAV, and the encoded heterologous gene product is a gene product not normally encoded by a naturally-occurring, wild-type AAV. An AAV including a nucleic acid encoding a variant capsid polypeptide includes a heterologous nucleic acid sequence. Once transferred/delivered into a host cell, a heterologous polynucleotide, contained within the virion, can be expressed (e.g., transcribed, and translated if appropriate). Alternatively, a transferred/delivered heterologous polynucleotide into a host cell, contained within the virion, need not be expressed. Although the term “heterologous” is not always used herein in reference to polynucleotides, reference to a polynucleotide even in the absence of the modifier “heterologous” is intended to include heterologous polynucleotides in spite of the omission.

The terms “genetic alteration” and “genetic modification” (and grammatical variants thereof), are used interchangeably herein to refer to a process wherein a genetic element (e.g., a polynucleotide) is introduced into a cell other than by mitosis or meiosis. The element may be heterologous to the cell, or it may be an additional copy or improved version of an element already present in the cell. Genetic alteration may be effected, for example, by transfecting a cell with a recombinant plasmid or other polynucleotide through any process known in the art, such as electroporation, calcium phosphate precipitation, or contacting with a polynucleotide-liposome complex. Genetic alteration may also be effected, for example, by transduction or infection with a DNA or RNA virus or viral vector. Generally, the genetic element is introduced into a chromosome or mini-chromosome in the cell; but any alteration changing the phenotype and/or genotype of the cell and its progeny is included in this term.

A cell is said to be “stably” altered, transduced, genetically modified, or transformed with a genetic sequence if the sequence is available to perform its function during extended culture of the cell in vitro. Generally, such a cell is “heritably” altered (genetically modified) in that a genetic alteration is introduced and inheritable by progeny of the altered cell.

The terms “polypeptide,” “peptide,” and “protein” are used interchangeably herein to refer to polymers of amino acids of any length. The “polypeptides,” “proteins” and “peptides” encoded by the “polynucleotide sequences,” include full-length native sequences, as with naturally occurring proteins, as well as functional subsequences, modified forms or sequence variants so long as the subsequence, modified form or variant retains some degree of functionality of the native full-length protein. In methods and uses of as described herein, such polypeptides, proteins and peptides encoded by the polynucleotide sequences can be but are not required to be identical to the defective endogenous protein, or whose expression is insufficient, or deficient in the treated mammal. The terms also encompass an modified amino acid polymer; for example, disulfide bond formation, glycosylation, lipidation, phosphorylation, or conjugation with a labeling component. Polypeptides such as anti-angiogenic polypeptides, neuroprotective polypeptides, and the like, when discussed in the context of delivering a gene product to a mammalian subject, and compositions therefor, refer to the respective intact polypeptide, or any fragment or genetically engineered derivative thereof, retaining the desired biochemical function of the intact protein.

As used herein, the abbreviations for the genetically encoded L-enantiomeric amino acids used in the disclosure methods are conventional and are as follows in Table 1.

In some embodiments, the polypeptide is a capsid polypeptide and the variant differs by at least one positive amino acid substitution. Positive amino acids include but are not limited to arginine, lysine and histidine. Amino acids also include naturally occurring and non-naturally occurring amino acids as well as derivatives thereof. Amino acids also include both D and L forms. Positive amino acids can also include non-naturally occurring amino acids as well as derivatives thereof. In some embodiments, a positive amino acid designation is pH dependent, with certain amino acids such as histidine being positive in some pH ranges and not positive in other pH ranges.

An “isolated” plasmid, nucleic acid, vector, virus, virion, host cell, or other substance refers to a preparation of the substance devoid of at least some of the other components present where the substance or a similar substance naturally occurs or from which it is initially prepared. Thus, for example, an isolated substance may be prepared by using a purification technique to enrich it from a source mixture. Enrichment can be measured on an absolute basis, such as weight per volume of solution, or it can be measured in relation to a second, potentially interfering substance present in the source mixture. Increasing enrichments of the embodiments of this invention are increasingly more isolated. An isolated plasmid, nucleic acid, vector, virus, host cell, or other substance is in some embodiments purified, e.g., from about 80% to about 90% pure, at least about 90% pure, at least about 95% pure, at least about 98% pure, or at least about 99%, or more, pure.

By the term “highly conserved” is meant at least about 80% identity, preferably at least 90% identity, and more preferably, over about 97% identity. Identity is readily determined by one of skill in the art by resort to algorithms and computer programs known by those of skill in the art.

The term “percent sequence identity” or “identical” in the context of nucleic acid sequences refers to the residues in the two sequences which are the same when aligned for maximum correspondence. The length of sequence identity comparison may be over the full-length of the genome, the full-length of a gene coding sequence, or a fragment of at least about 500 to 5000 nucleotides, is desired. However, identity among smaller fragments, e.g. of at least about nine nucleotides, usually at least about 20 to about 24 nucleotides, at least about 28 to about 32 nucleotides, at least about 36 or more nucleotides, may also be desired. Similarly, “percent sequence identity” may be readily determined for amino acid sequences, over the full-length of a protein, or a fragment thereof. Suitably, a fragment is at least about 8 amino acids in length, and may be up to about 700 amino acids.

As used herein, the terms “treatment,” “treating,” and the like, refer to obtaining a desired pharmacologic and/or physiologic effect. The effect may be prophylactic in terms of completely or partially preventing a disease or symptom thereof and/or may be therapeutic in terms of a partial or complete cure for a disease and/or adverse effect attributable to the disease. “Treatment,” as used herein, covers any treatment of a disease in a mammal, particularly in a human, and includes: (a) preventing the disease from occurring in a subject predisposed to the disease or at risk of acquiring the disease but has not yet been diagnosed as having it; (b) inhibiting the disease, i.e., arresting its development; and (c) relieving the disease, i.e., causing regression of the disease.

The terms “individual,” “subject,” and “patient” are used interchangeably herein, and refer to a mammal, including, but not limited to, human and non-human primates, including simians and humans; mammalian sport animals (e.g., horses); mammalian farm animals (e.g., sheep, goats, etc.); mammalian pets (dogs, cats, etc.); and rodents (e.g., mice, rats, etc.).

The terms “pharmaceutically acceptable” and “physiologically acceptable” mean a biologically acceptable formulation, gaseous, liquid or solid, or mixture thereof, suitable for one or more routes of administration, in vivo delivery or contact. A “pharmaceutically acceptable” or “physiologically acceptable” composition is a material that is not biologically or otherwise undesirable, e.g., the material may be administered to a subject without causing substantial undesirable biological effects. Thus, such a pharmaceutical composition may be used, for example in administering a AAV vector or AAV virion as disclosed herein, or transformed cell to a subject.

The phrase a “unit dosage form” as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity optionally in association with a pharmaceutical carrier (excipient, diluent, vehicle or filling agent) which, when administered in one or more doses, produces a desired effect (e.g., prophylactic or therapeutic effect). In some embodiments, unit dosage forms may be within, for example, ampules and vials, including a liquid composition, or a composition in a freeze-dried or lyophilized state; a sterile liquid carrier, for example, can be added prior to administration or delivery in vivo. Individual unit dosage forms can be included in multi-dose kits or containers. AAV vectors or AAV virions, and pharmaceutical compositions thereof can be packaged in single or multiple unit dosage form for ease of administration and uniformity of dosage.

A “therapeutically effective amount” will fall in a relatively broad range determinable through experimentation and/or clinical trials. For example, for in vivo injection, e.g., injection directly into the eye, a therapeutically effective dose will be on the order of from about 10⁶ to about 10¹⁵ of the AAV virions, e.g., from about 10⁸ to 10¹² AAV virions. For example, for in vivo injection, e.g., injection directly into the eye, a therapeutically effective dose will be on the order of from about 10⁶ to about 10¹⁵ infectious units, e.g., from about 10⁸ to about 10¹² infectious units. Other effective dosages can be readily established by one of ordinary skill in the art through routine trials establishing dose response curves.

An “effective amount” or “sufficient amount” refers to an amount providing, in single or multiple doses, alone or in combination, with one or more other compositions (therapeutic agents such as a drug), treatments, protocols, or therapeutic regimens agents, a detectable response of any duration of time (long or short term), an expected or desired outcome in or a benefit to a subject of any measurable or detectable degree or for any duration of time (e.g., for minutes, hours, days, months, years, or cured).

The doses of an “effective amount” or “sufficient amount” for treatment (e.g., to ameliorate or to provide a therapeutic benefit or improvement) typically are effective to provide a response to one, multiple or all adverse symptoms, consequences or complications of the disease, one or more adverse symptoms, disorders, illnesses, pathologies, or complications, for example, caused by or associated with the disease, to a measurable extent, although decreasing, reducing, inhibiting, suppressing, limiting or controlling progression or worsening of the disease is a satisfactory outcome.

“Prophylaxis” and grammatical variations thereof mean a method in which contact, administration or in vivo delivery to a subject is prior to disease. Administration or in vivo delivery to a subject can be performed prior to development of an adverse symptom, condition, complication, etc. caused by or associated with the disease. For example, a screen (e.g., genetic) can be used to identify such subjects as candidates for the described methods and uses, but the subject may not manifest the disease. Such subjects therefore include those screened positive for an insufficient amount or a deficiency in a functional gene product (protein), or producing an aberrant, partially functional or non-functional gene product (protein), leading to disease; and subjects screening positive for an aberrant, or defective (mutant) gene product (protein) leading to disease, even though such subjects do not manifest symptoms of the disease.

As used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an AAV virion” includes a plurality of such virions and reference to “a host cell” includes reference to one or more host cells and equivalents thereof known to those skilled in the art, and so forth. It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely,” “only” and the like in connection with the recitation of claim elements, or use of a “negative” limitation.

Before the invention is further described, it is to be understood that this invention is not limited to particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

AAV Vector Features

AAV vectors of the present invention on have numerous features. In some embodiments, the vectors comprise nucleic acid sequences encoding for variant capsid polypeptides. In some embodiments, the variant capsid polypeptide is more cationic than an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide, thus allowing the AAV vector to contain a longer nucleic acid insert. Such AAV vectors and their features are described in detail below.

An exemplary AAV vector of the present invention comprise a nucleic acid encoding for a variant AAV capsid protein differing in amino acid sequence by at least one amino acid from a wild-type or non-variant parent capsid protein. The amino acid difference(s) can be located in a solvent accessible site in the capsid, e.g., a solvent-accessible loop, or in the lumen (i.e., the interior space of the AAV capsid). In some embodiments, the lumen includes the interior space of the AAV capsid. For example, the amino acid substitution(s) can be located in a GH loop in the AAV capsid polypeptide. In some embodiments, the variant capsid polypeptide comprises an amino acid substitution in AAV1, AAV3, AAV4, AAV5, AAV6, AAV7, or AAV8 capsid polypeptides.

In some embodiments, the present invention provides an isolated nucleic acid comprising a nucleotide sequence that encodes a variant adeno-associated virus (AAV) capsid protein, where the variant AAV capsid protein comprises an amino acid sequence having at least about 85% at least about 90%, at least about 95%, at least about 98%, at least about 99%, or 100%, to non-variant capsid amino acid sequences, such as those capsid sequences listed in SEQ ID NOs: 1-95 and where the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the substitutions include one or more substitutions according to FIG. 7A-7C, including substitution at one or more positions as listed in FIG. 7A-7C. In some embodiments, substitution is at one or more of residues selected from the group consisting of: 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 229, 231, 232, 233, 234, 235, 236, 237, 238, 240, 242, 300, 304, 305, 306, 309, 311, 312, 314, 316, 345, 346, 347, 348, 349, 350, 351, 399, 400, 401, 402, 403, 408, 409, 410, 411, 412, 413, 414, 415, 416, 417, 418, 419, 420, 421, 422, 423, 424, 426, 625, 626, 627, 628, 629, 630, 631, 632, 633, 638, 639, 640, 642, 643, 681, 683, 685, 687, 688, 689, 690, 691, 692, 693, and 694. In some embodiments, the substitutions include one or more substitutions at the lumenal positions defined and shown according to FIG. 10. In some embodiments, the AAV capsid polypeptide is not an amino acid sequence corresponding to a naturally occurring AAV capsid polypeptide. In some embodiments, the present invention provides an isolated nucleic acid comprising a nucleotide sequence that encodes a variant adeno-associated virus (AAV) capsid protein, where the variant AAV capsid protein comprises an amino acid sequence having at least about 85% at least about 90%, at least about 95%, at least about 98%, at least about 99%, or 100%, to non-variant capsid amino acid sequences, such as wild-type AAV1, AAV3, AAV4, AAV5, AAV6, AAV7, or AAV8 capsid polypeptides, and where the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide based on the non-variant capsid parental lumenal charge. In some embodiments, the non-variant capsid parental lumenal charge is based on the percent lumen exposure. In some embodiments, the percent lumen exposure for the non-variant parent capsid polypeptide is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%. In some embodiments, the percent lumen exposure for the non-variant parent capsid polypeptide is 10%, 20%, 30%, or 40%. In some embodiments, the percent lumen exposure for the non-variant parent capsid polypeptide is 10%. In some embodiments, the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide based on the non-variant capsid parental lumenal charge when the percent lumen exposure for the non-variant parent capsid polypeptide and/or another variant capsid polypeptide is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%. In some embodiments, the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide based on the non-variant capsid parental lumenal charge when the percent lumen exposure for the non-variant parent capsid polypeptide and/or another variant capsid polypeptide is 10%, 20%, 30%, or 40%. In some embodiments, the variant capsid polypeptide is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide based on the non-variant capsid parental lumenal charge when the percent lumen exposure for the non-variant parent capsid polypeptide and/or another variant capsid polypeptide is 10%.

In some embodiments, the variant capsid sequence is selected from the group consisting of the sequences listed below.

Some embodiments, a subject AAV vector can encode a variant capsid polypeptide having an amino acid sequence of at least about 85%, at least about 90%, at least about 95%, at least about 98%, or at least about 99%, or 100%, amino acid sequence identity to non-variant parent capsid polypeptide and/or another variant capsid polypeptide, where the variant AAV capsid protein comprises from 1 to about 10 positive amino acid differences (e.g., amino acid substitutions and/or amino acid insertions and/or amino acid deletions) compared to the non-variant parent capsid polypeptide and/or another variant capsid polypeptide sequence. The amino acid difference(s) can be located in a solvent accessible site in the capsid, e.g., a solvent-accessible loop. For example, the amino acid substitution(s) can be located in a GH loop in the AAV capsid polypeptide.

In some embodiments, the variant capsid polypeptides exhibit substantial homology or “substantial similarity,” when referring to amino acids or fragments thereof, indicates that, when optimally aligned with appropriate amino acid insertions or deletions with another amino acid (or its complementary strand), there is amino acid sequence identity in at least about 95 to about 99% of the aligned sequences. In some embodiments, the homology is over full-length sequence, or a polypeptide thereof, e.g., a capsid protein, a rep (replication) protein, or a fragment thereof of at least 8 amino acids, or more desirably, at least about 15 amino acids in length. For example, the variant capsid polypeptide can comprise an amino acid sequence having at least about 85%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or 100%, amino acid sequence identity to a parent capsid polypeptide. In some embodiments the parent capsid polypeptide sequence comprises SEQ ID NOs: 1-95.

The variant capsid polypeptides of the present invention exhibit an overall increase in positive charge as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the non-variant parent capsid polypeptide and/or another variant capsid polypeptide is the starting polypeptide sequence that is then substituted at the amino acid level to provide the variant capsid polypeptide with an increase in overall positive charge as compared to the non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide of the AAV vector described herein comprises at least 1 additional positive amino acid substitution compared to an otherwise substantially identical non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide of the AAV vector described herein comprises at least 1 positive amino acid substitution to at least 7 positive amino acid substitutions as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide of the AAV vector described herein comprises at least 1 positive amino acid substitution, at least 2 positive amino acid substitutions, at least 3 positive amino acid substitutions, at least 4 positive amino acid substitutions, at least 5 positive amino acid substitutions, at least 6 positive amino acid substitutions, at least 7 positive amino acid substitutions, at least 8 positive amino acid substitutions, at least 9 positive amino acid substitutions, at least 10 positive amino acid substitutions, at least 11 positive amino acid substitutions, at least 12 positive amino acid substitution, at least 13 positive amino acid substitutions, at least 14 positive amino acid substitution, at least 15 positive amino acid substitutions, at least 16 positive amino acid substitution, at least 17 positive amino acid substitutions, at least 18 positive amino acid substitution, at least 19 positive amino acid substitutions, or at least 20 positive amino acid substitutions, as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide encoded by the AAV vectors described herein comprises at least a +1 lumenal charge as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide comprises at least a +1 lumenal charge to at least a +15 lumenal charge as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide of the AAV vector described herein comprises at least a +1 lumenal charge to at least a +7 lumenal charge as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide of the AAV vector described herein comprises at least a +1 lumenal charge, +2 lumenal charge, +3 lumenal charge, +4 lumenal charge, +5 lumenal charge, +6 lumenal charge, +7 lumenal charge, +8 lumenal charge, +9 lumenal charge, +10 lumenal charge, +11 lumenal charge, +12 lumenal charge, +13 lumenal charge, +14 lumenal charge, +15 lumenal charge, +16 lumenal charge, +17 lumenal charge, +18 lumenal charge, +19 lumenal charge, +20 lumenal charge, +21 lumenal charge, +22 lumenal charge, +23 lumenal charge, +24 lumenal charge, or a +25 lumenal charge, or more as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the variant capsid polypeptide is made more cationic by substituting one or more amino acids selected from positive amino acids in order to generate a capsid polypeptide that is more cationic as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the positive amino acids include but are not limited to arginine (Arg, R), lysine (Lys, K) and histidine (His, H) and derivatives thereof. In some embodiments, amino acids substituted in the variant capsid polypeptide include naturally occurring and non-naturally occurring positive amino acids as well as derivatives thereof. Positive amino acids can include non-naturally occurring amino acids as well as derivatives thereof. In some embodiments, the more cationic capsid polypeptide allows packing increased nucleic acid insert lengths into the AAV virion.

In some embodiments, a positive amino acid designation is not pH dependent. For example, the amino acid can have a non-pH-dependent quaternary amine. Non-pH dependent positive amino acids include but are not limited to arginine and lysine.

In some embodiments, a positive amino acid designation is pH dependent, with certain amino acids exhibiting a positive charge in one pH range but not in another pH range.

In some embodiments, the positive amino acid for substituted in to the polypeptide is a pH switchable amino acid, wherein the charge state of the amino acid changes dependent upon the pH of the environment. In some embodiments, the variant capsid polypeptide is made more cationic by substituting one or more negative amino acids with one or more neutral and/or positive amino acids in order to make the overall charge of the variant capsid polypeptide more positive than the otherwise substantially identical wild-type capsid polypeptide (i.e., the non-variant parent capsid polypeptide) and/or another variant capsid polypeptide as described herein. Negative amino acids include but are not limited to aspartic acid (Asp, D) and glutamic acid (Glu, E) and derivatives thereof. Neutral amino acids include non-positive and non-negative amino acids. Neutral amino acids include but are not limited to alanine (Ala, A), asparagine (Asn, N), aspartic acid (Asp, D), cysteine (Cys, C), glutamine (Gln, Q), glycine (Gly, G), isoleucine (Ile, I), leucine (Leu, L), methionine (Met, M), phenylalanine (Phe, F), proline (Pro, P), serine (Ser, S), threonine (Thr, T), tryptophan (Trp, W), tyrosine (Tyr, Y), and valine (Val, V) and derivatives thereof.

The nucleic acid insert (also referred to as a heterologous nucleotide sequence) can be operably linked to control elements directing the transcription or expression thereof in the nucleotide sequence in vivo. Such control elements can comprise control sequences normally associated with the selected gene (e.g., endogenous cellular control elements). Alternatively, heterologous control sequences can be employed. Useful heterologous control sequences generally include those derived from sequences encoding mammalian or viral genes.

Such promoter sequences are commercially available from, e.g., Stratagene (San Diego, Calif.).

In some embodiments, a cell type-specific or a tissue-specific promoter can be operably linked to nucleic acid insert (also referred to as a heterologous nucleotide sequence) encoding the heterologous gene product, and allowing for selectively or preferentially producing a gene product in a particular cell type(s) or tissue(s). In some embodiments, an inducible promoter can be operably linked to the heterologous nucleic acid.

The AAV vectors of the present invention encode a variant capsid polypeptide exhibiting an overall increase in positive charge as compared to a non-variant parent capsid polypeptide and/or another variant capsid polypeptide allows for an increased nucleic acid insert length as compared to an AAV vector encoding the non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, a positive increase in the lumenal charge of the variant capsid polypeptide results in an increase in the length of the longer nucleic acid the AAV vector is capable of containing.

In some embodiments, the longer nucleic acid insert is at least 10% longer. In some embodiments, the longer nucleic acid insert is at least 15% longer. In some embodiments, the longer nucleic acid insert is at least 20% longer. In some embodiments, the longer nucleic acid insert is at least 25% longer.

Purified infectious AAV virions contain three major structural proteins designated VP1, VP2, and VP3 (87, 73, and 62 kDa, respectively) in an approximate ratio of 1:1:18. In some embodiments, the AAV vector has portions of the AAV vector deleted, in order to allow for more space during AAV vector packaging into an AAV virion. In some embodiments, additional sequences are deleted from the AAV vector, including but not limited to the VP2 capsid proteins (a capsid protein not required for viral infectivity), as well as other portions of the AAV vector including those described herein. In some embodiments, the deleted sequences allow for increased volume in order to package AAV vectors with increased nucleic acid insert lengths into the AAV virion as described herein. In some embodiments, the deleted sequences allow for increased interaction with a positive charge in order to package AAV vectors with increased nucleic acid insert lengths into the AAV virion as described herein.

The AAV vectors or AAV virions disclosed herein can also include conventional control elements operably linked to the nucleic acid insert (also referred to as a heterologous nucleotide sequence) in a manner permitting transcription, translation and/or expression in a cell transfected with the AAV vector or infected with the AAV virion produced according to the present invention. As used herein, “operably linked” sequences include both expression control sequences that are contiguous with the gene of interest and expression control sequences that act in trans or at a distance to control the gene of interest.

Expression control sequences include appropriate transcription initiation, termination, promoter and enhancer sequences; efficient RNA processing signals such as splicing and polyadenylation (polyA) signals; sequences that stabilize cytoplasmic mRNA; sequences that enhance translation efficiency (i.e., Kozak consensus sequence); sequences that enhance protein stability; and when desired, sequences that enhance secretion of the encoded product. A great number of expression control sequences, including promoters selected from native, constitutive, inducible and/or tissue-specific, are known in the art and may be utilized.

Examples of constitutive promoters include, without limitation, the retroviral Rous sarcoma virus (RSV) LTR promoter (optionally with the RSV enhancer), the cytomegalovirus (CMV) promoter (optionally with the CMV enhancer) (see, e.g., Boshart et al., Cell, 41:521-530 (1985)), the SV40 promoter, the dihydrofolate reductase promoter, the .beta.-actin promoter, the phosphoglycerol kinase (PGK) promoter, and the EF1 promoter (Invitrogen). Inducible promoters allow regulation of gene expression and can be regulated by exogenously supplied compounds, environmental factors such as temperature, or the presence of a specific physiological state, e.g., acute phase, a particular differentiation state of the cell, or in replicating cells only. Inducible promoters and inducible systems are available from a variety of commercial sources, including, without limitation, Invitrogen, Clonetech and Ariad. Many other systems have been described and can be readily selected by one of skill in the art. Examples of inducible promoters regulated by exogenously supplied compounds, include, the zinc-inducible sheep metallothionine (MT) promoter, the dexamethasone (Dex)-inducible mouse mammary tumor virus (MMTV) promoter, the T7 polymerase promoter system (WO 98/10088); the ecdysone insect promoter (No et al., (1996) Proc. Natl. Acad. Sci. USA, 93:3346-3351), the tetracycline-repressible system (Gossen et al., (1992) Proc. Natl. Acad. Sci. USA, 89:5547-5551), the tetracycline-inducible system (Gossen et al., (1995) Science, 268:1766-1769, see also Harvey et al., (1998) Curr. Opin. Chem. Biol., 2:512-518), the RU486-inducible system (Wang et al., (1997) Nat. Biotech., 15:239-243 and Wang et al., (1997) Gene Ther., 4:432-441) and the rapamycin-inducible system (Magari et al., (1997) J. Clin. Invest., 100:2865-2872). Other types of inducible promoters useful in this context are those regulated by a specific physiological state, e.g., temperature, acute phase, a particular differentiation state of the cell, or in replicating cells only.

In another embodiment, the native promoter for the nucleic acid insert (also referred to as a heterologous nucleotide sequence) will be used. The native promoter may be preferred when it is desired that expression of the nucleic acid insert (also referred to as a heterologous nucleotide sequence) should mimic the native expression. The native promoter may be used when expression of the nucleic acid insert (also referred to as a heterologous nucleotide sequence) must be regulated temporally or developmentally, or in a tissue-specific manner, or in response to specific transcriptional stimuli. In a further embodiment, other native expression control elements, such as enhancer elements, polyadenylation sites or Kozak consensus sequences may also be used to mimic the native expression.

Another embodiment of the nucleic acid insert (also referred to as a heterologous nucleotide sequence) includes a gene operably linked to a tissue-specific promoter. For instance, if expression in skeletal muscle is desired, a promoter active in muscle should be used. These include the promoters from genes encoding skeletal (3-actin, myosin light chain 2A, dystrophin, muscle creatine kinase, as well as synthetic muscle promoters with activities higher than naturally-occurring promoters (see Li et al., Nat. Biotech., 17:241-245 (1999)). Examples of promoters that are tissue-specific are known for liver (albumin, Miyatake et al., (1997) J. Virol., 71:5124-32; hepatitis B virus core promoter, Sandig et al., (1996) Gene Ther., 3:1002-9; alpha-fetoprotein (AFP), Arbuthnot et al., (1996) Hum. Gene Ther., 7:1503-14), bone osteocalcin (Stein et al., (1997) Mol. Biol. Rep., 24:185-96); bone sialoprotein (Chen et al., (1996) J. Bone Miner. Res., 11:654-64), lymphocytes (CD2, Hansal et al., (1998) J. Immunol., 161:1063-8; immunoglobulin heavy chain; T cell receptor chain), neuronal such as neuron-specific enolase (NSE) promoter (Andersen et al., (1993) Cell. Mol. Neurobiol., 13:503-15), neurofilament light-chain gene (Piccioli et al., (1991) Proc. Natl. Acad. Sci. USA, 88:5611-5), and the neuron-specific vgf gene (Piccioli et al., (1995) Neuron, 15:373-84), among others.

In various embodiments, AAV vectors or AAV virions carrying one or more therapeutically useful nucleic acid insert (also referred to as a heterologous nucleotide sequence) also include selectable markers or reporter genes, e.g., sequences encoding geneticin, hygromycin or puromycin resistance, among others. Selectable reporters or marker genes can be used to signal the presence of the plasmids/vectors in bacterial cells, including, for example, examining ampicillin resistance. Other components of the plasmid may include an origin of replication. Selection of these and other promoters and vector elements are conventional and many such sequences are available (see, e.g., Sambrook et al., and references cited therein).

Host Cells and Packaging

Host cells are necessary for generating infection AAV vectors as well as for generating AAV virions based on the disclosed AAV vectors. Accordingly, the present invention provides host cells for generation and packaging of AAV virions based on the AAV vectors of the present invention. A variety of host cells are known in the art and can find use in the methods of the present invention. Any host cells described herein or known in the art can be employed with the compositions and methods described herein.

The present invention provides host cells, e.g., isolated (genetically modified) host cells, comprising a subject nucleic acid. A subject host cell can be an isolated cell, e.g., a cell in in vitro culture. A subject host cell is useful for producing a subject AAV vector or AAV virion, as described below. Where a subject host cell is used to produce a subject AAV virion, it is referred to as a “packaging cell.” In some embodiments, a subject host cell is stably genetically modified with a subject AAV vector. In other embodiments, a subject host cell is transiently genetically modified with a subject AAV vector.

In some embodiments, a subject nucleic acid is introduced stably or transiently into a host cell, using established techniques, including, but not limited to, electroporation, calcium phosphate precipitation, liposome-mediated transfection, baculovirus infection, and the like. For stable transformation, a subject nucleic acid will generally further include a selectable marker, e.g., any of several well-known selectable markers such as neomycin resistance, and the like.

Generally, when delivering the AAV vector according to the present invention by transfection, the AAV vector is delivered in an amount from about 5 μg to about 100 μg DNA, about 10 to about 50 μg DNA to about 1×10⁴ cells to about 1×10¹³ cells, or about 1×10⁵ cells. However, the relative amounts of vector DNA to host cells may be adjusted, taking into consideration such factors as the selected vector, the delivery method and the host cells selected and such adjustments are within the level of skill of one in the art.

In some embodiments, the host cell itself may be selected from any biological organism, including prokaryotic (e.g., bacterial) cells, and eukaryotic cells, including, insect cells, yeast cells and mammalian cells. A subject host cell is generated by introducing a subject nucleic acid into any of a variety of cells, e.g., mammalian cells, including, e.g., murine cells, and primate cells (e.g., human cells). Particularly desirable host cells are selected from among any mammalian species, including, without limitation, cells such as A549, WEHI, 3T3, 10T1/2, BHK, MDCK, COS 1, COS 7, BSC 1, BSC 40, BMT 10, VERO, WI38, HeLa, CHO, 293, Vero, NIH 3T3, PC12, Huh-7 Saos, C2C12, RAT1, Sf9, L cells, HT1080, human embryonic kidney (HEK), HLHepG2, HepG2 and primary fibroblast, hepatocyte and myoblast cells derived from mammals including human, monkey, mouse, rat, rabbit, and hamster. The selection of the mammalian species providing the cells is not a limitation of this invention; nor is the type of mammalian cell, i.e., fibroblast, hepatocyte, tumor cell, etc. The requirements for the cell used is it is capable of infection or transfection by an AAV vector. In some embodiments, the host cell is one that has rep and capsid stably transfected in the cell, including a variant capsid as described herein. In some embodiments, the host cell expresses part of the AAV vector, such as the heterologous nucleic acid sequence.

In some embodiments, the preparation of a host cell according to the invention involves techniques such as assembly of selected DNA sequences. This assembly may be accomplished utilizing conventional techniques. Such techniques include cDNA and genomic cloning, which are well known and are described in Sambrook et al., cited above, use of overlapping oligonucleotide sequences of the adenovirus and AAV genomes, combined with polymerase chain reaction, synthetic methods, and any other suitable methods providing the desired nucleotide sequence.

In some embodiments, introduction of the AAV vector into the host cell may also be accomplished using techniques known to the skilled artisan and as discussed throughout the specification. In a preferred embodiment, standard transfection techniques are used, e.g., CaPO₄ transfection or electroporation, and/or infection by hybrid adenovirus/AAV vectors into cell lines such as the human embryonic kidney cell line HEK 293 (a human kidney cell line containing functional adenovirus El genes providing trans-acting El proteins).

In some embodiments, a subject genetically modified host cell includes, in addition to a nucleic acid comprising a nucleotide sequence encoding a variant AAV capsid protein, as described above, a nucleic acid that comprises a nucleotide sequence encoding one or more AAV rep (replication) proteins. In other embodiments, a subject host cell further comprises an AAV vector. An AAV virion can be generated using a subject host cell. Methods of generating an AAV virion are described in, e.g., U.S. Patent Publication No. 2005/0053922 and U.S. Patent Publication No. 2009/0202490.

In addition to the AAV vector, in exemplary embodiments, the host cell contains the sequences driving expression of the AAV capsid polypeptide (including variant capsid polypeptides and non-variant parent capsid polypeptides) in the host cell and rep (replication) sequences of the same serotype as the serotype of the AAV Inverted Terminal Repeats (ITRs) found in the nucleic acid insert (also referred to as a heterologous nucleotide sequence), or a cross-complementing serotype. The AAV capsid and rep (replication) sequences may be independently obtained from an AAV source and may be introduced into the host cell in any manner known to one of skill in the art or as described herein. Additionally, when pseudotyping an AAV vector in an AAV8 capsid, the sequences encoding each of the essential rep (replication) proteins may be supplied by AAV8, or the sequences encoding the rep (replication) proteins may be supplied by different AAV serotypes (e.g., AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV9).

In some embodiments, the host cell stably contains the capsid protein under the control of a suitable promoter (including, for example, the variant capsid polypeptides of the invention), such as those described above. In some embodiments, the capsid protein is expressed under the control of an inducible promoter. In some embodiments, the capsid protein is supplied to the host cell in trans. When delivered to the host cell in trans, the capsid protein may be delivered via a plasmid containing the sequences necessary to direct expression of the selected capsid protein in the host cell. In some embodiments, when delivered to the host cell in trans, the vector encoding the capsid protein (including, for example, the variant capsid polypeptides of the invention) also carries other sequences required for packaging the AAV, e.g., the rep (replication) sequences.

In some embodiments, the host cell stably contains the rep (replication) sequences under the control of a suitable promoter, such as those described above. In some embodiments, the essential rep (replication) proteins are expressed under the control of an inducible promoter. In another embodiment, the rep (replication) proteins are supplied to the host cell in trans. When delivered to the host cell in trans, the rep (replication) proteins may be delivered via a plasmid containing the sequences necessary to direct expression of the selected rep (replication) proteins in the host cell. In some embodiments, when delivered to the host cell in trans, the vector encoding the capsid protein (including, for example, the variant capsid polypeptides of the invention) also carries other sequences required for packaging the AAV vector, e.g., the rep (replication) sequences.

In some embodiments, the rep (replication) and capsid sequences may be transfected into the host cell on a single nucleic acid molecule and exist stably in the cell as an episome. In another embodiment, the rep (replication) and capsid sequences are stably integrated into the chromosome of the cell. Another embodiment has the rep (replication) and capsid sequences transiently expressed in the host cell. For example, a useful nucleic acid molecule for such transfection comprises, from 5′ to 3′, a promoter, an optional spacer interposed between the promoter and the start site of the rep (replication) gene sequence, an AAV rep (replication) gene sequence, and an AAV capsid gene sequence.

Although the molecule(s) providing rep (replication) and capsid can exist in the host cell transiently (i.e., through transfection), in some embodiments, one or both of the rep (replication) and capsid proteins and the promoter(s) controlling their expression be stably expressed in the host cell, e.g., as an episome or by integration into the chromosome of the host cell. The methods employed for constructing embodiments of the invention are conventional genetic engineering or recombinant engineering techniques such as those described in the references above.

In some embodiments, the packaging host cell can require helper functions in order to package the AAV vector of the invention into an AAV virion. In some embodiments, these functions may be supplied by a herpesvirus. In some embodiments, the necessary helper functions are each provided from a human or non-human primate adenovirus source, and are available from a variety of sources, including the American Type Culture Collection (ATCC), Manassas, Va. (US). In some embodiments, the host cell is provided with and/or contains an E1a gene product, an E1b gene product, an Eta gene product, and/or an E4 ORF6 gene product. In some embodiments, the host cell may contain other adenoviral genes such as VAI RNA. In some embodiments, no other adenovirus genes or gene functions are present in the host cell.

In some embodiments, the variant capsid polypeptide that is more cationic allows for similar nucleic acid release from the capsid polypeptide as a non-variant parent capsid polypeptide and/or another variant capsid polypeptide. In some embodiments, the variant capsid polypeptide that is more cationic allows for nucleic acid release from the capsid that is about 95%, about 90%, about 85%, about 80%, about 75%, about 70% of the amount released from a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, useful heterologous nucleic acid sequence products include those used for treatment of hemophilia, including hemophilia B (including Factor IX) and hemophilia A (including Factor VIII and its variants, such as the light chain and heavy chain of the heterodimer and the B-deleted domain; U.S. Pat. No. 6,200,560 and U.S. Pat. No. 6,221,349). The Factor VIII gene codes for 2351 amino acids and the protein has six domains, designated from the amino to the terminal carboxy terminus as A1-A2-B-A3-C1-C2 (Wood et al., (1984) Nature, 312:330; Vehar et al., (1984) Nature 312:337; and Toole et al., (1984) Nature, 342:337). Human Factor VIII is processed within the cell to yield a heterodimer primarily comprising a heavy chain containing the A1, A2 and B domains and a light chain containing the A3, C1 and C2 domains. Both the single chain polypeptide and the heterodimer circulate in the plasma as inactive precursors, until activated by thrombin cleavage between the A2 and B domains, releasing the B domain and results in a heavy chain consisting of the Al and A2 domains. The B domain is deleted in the activated procoagulant form of the protein. Additionally, in the native protein, two polypeptide chains (“a” and “b”), flanking the B domain, are bound to a divalent calcium cation.

In some embodiments, the heterologous nucleic acid sequence comprises the first 57 base pairs of the Factor VIII heavy chain encoding the 10 amino acid signal sequence, as well as the human growth hormone (hGH) polyadenylation sequence. n alternative embodiments, the heterologous nucleic acid sequence further comprises the A1 and A2 domains, as well as 5 amino acids from the N-terminus of the B domain, and/or 85 amino acids of the C-terminus of the B domain, as well as the A3, C1 and C2 domains. In yet other embodiments, the nucleic acids encoding Factor VIII heavy chain and light chain are provided in a single heterologous nucleic acid sequence separated by 42 nucleic acids coding for 14 amino acids of the B domain (U.S. Pat. No. 6,200,560).

As used herein, a therapeutically effective amount is an amount of AAV vector that produces sufficient amounts of Factor VIII to decrease the time it takes for a subject's blood to clot. Generally, severe hemophiliacs having less than 1% of normal levels of Factor VIII have a whole blood clotting time of greater than 60 minutes as compared to approximately 10 minutes for non-hemophiliacs.

The present invention is not limited to any specific Factor VIII sequence. Many natural and recombinant forms of Factor VIII have been isolated and generated. Examples of naturally occurring and recombinant forms of Factor VII can be found in the patent and scientific literature including, U.S. Pat. No. 5,563,045, U.S. Pat. No. 5,451,521, U.S. Pat. No. 5,422,260, U.S. Pat. No. 5,004,803, U.S. Pat. No. 4,757,006, U.S. Pat. No. 5,661,008, U.S. Pat. No. 5,789,203, U.S. Pat. No. 5,681,746, U.S. Pat. No. 5,595,886, U.S. Pat. No. 5,045,455, U.S. Pat.

No. 4,886,876, WO 94/11503, WO 87/07144, WO 92/16557, WO 91/09122, WO 97/03195, WO 96/21035, WO 91/07490, EP 0 672 138, EP 0 270 618, EP 0 182 448, EP 0 162 067, EP 0 786 474, EP 0 533 862, EP 0 506 757, EP 0 874 057, EP 0 795 021, EP 0 670 332, EP 0 500 734, EP 0 232 112, EP 0 160 457, Sanberg et al., Int. Congress of the World Fed. Of Hemophilia (1992), and Lind et al., Eur. J. Biochem., 232:19 (1995); all of which are incorporated herein by reference in their entireties.

Nucleic acid sequences coding for the above-described Factor VIII can be obtained using recombinant methods or by deriving the sequence from a vector known to include the same. Furthermore, the desired sequence can be isolated directly from cells and tissues containing the same, using standard techniques, such as phenol extraction and PCR of cDNA or genomic DNA (See, e.g., Sambrook et al). Nucleotide sequences can also be produced synthetically, rather than cloned. The complete sequence can be assembled from overlapping oligonucleotides prepared by standard methods and assembled into a complete coding sequence (See, e.g., Edge,(1981) Nature 292:757; Nambari et al., (1984) Science, 223:1299; and Jay et al., (1984) J. Biol. Chem. 259:6311.

Furthermore, the disclosed methods are not limited to human Factor VIII. Indeed, it is intended that the present invention encompass Factor VIII from animals other than humans, including but not limited to companion animals (e.g., canine, felines, and equines), livestock (e.g., bovines, caprines and ovines), laboratory animals, marine mammals, large cats, etc.

The AAV vectors may contain a nucleic acid coding for non-biologically active fragments of Factor VIII, yet when administered into the subject improves or restores the blood clotting time. For example, as discussed above, the Factor VIII protein comprises two polypeptide chains: a heavy chain and a light chain separated by B-domain cleavage during processing. As demonstrated by the present invention, co-traducing recipient cells with the Factor VIII heavy and light chains leads to the expression of biologically active Factor VIII. Because, however, most hemophiliacs contain a mutation or deletion in only one of the chain (e.g., heavy or light chain), it may be possible to administer only the chain defective in the patient to supply the other chain.

In some embodiments, useful gene products include non-naturally occurring polypeptides, such as chimeric or hybrid polypeptides having a non-naturally occurring amino acid sequence containing insertions, deletions or amino acid substitutions. For example, single-chain engineered immunoglobulins could be useful in certain immunocompromised patients. Other types of non-naturally occurring gene sequences include antisense molecules and catalytic nucleic acids, such as ribozymes, used to reduce overexpression of a target.

Reduction and/or modulation of expression of a heterologous nucleic acid sequence is particularly desirable for treatment of hyperproliferative conditions characterized by hyperproliferating cells, as are cancers and psoriasis. Target polypeptides include those polypeptides produced exclusively or at higher levels in hyperproliferative cells as compared to normal cells. Target antigens include polypeptides encoded by oncogenes such as myb, myc, ftn, and the translocation gene bcr/abl, ras, src, P53, neu, trk and EGRF. In addition to oncogene products as target antigens, target polypeptides for anti-cancer treatments and protective regimens include variable regions of antibodies made by B cell lymphomas and variable regions of T cell receptors of T cell lymphomas which, in some embodiments, are used as target antigens for autoimmune disease. Other tumor-associated polypeptides can be used as target polypeptides such as polypeptides found at higher levels in tumor cells including the polypeptide recognized by monoclonal antibody 17-1A and folate binding polypeptides.

In some embodiments, suitable therapeutic polypeptides and proteins include those useful for treating individuals suffering from autoimmune diseases and disorders by conferring a broad based protective immune response against targets that are associated with autoimmunity including cell receptors and cells producing “self”-directed antibodies. T cell mediated autoimmune diseases include Rheumatoid arthritis (RA), multiple sclerosis (MS), Sjogren's syndrome, sarcoidosis, insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, reactive arthritis, ankylosing spondylitis, scleroderma, polymyositis, dermatomyositis, psoriasis, vasculitis, Wegener's granulomatosis, Crohn's disease and ulcerative colitis. Each of these diseases is characterized by T cell receptors (TCRs) that bind to endogenous antigens and initiate the inflammatory cascade associated with autoimmune diseases.

In some embodiments, heterologous nucleic acid sequences encode for immunogens useful to immunize a human or non-human animal against other pathogens including bacteria, fungi, parasitic microorganisms or multicellular parasites infecting human and non-human vertebrates, or from a cancer cell or tumor cell. Examples of bacterial pathogens include pathogenic gram-positive cocci include pneumococci; staphylococci (and the toxins produced thereby, e.g., enterotoxin B); and streptococci. Pathogenic gram-negative cocci include meningococcus; gonococcus. Pathogenic enteric gram-negative bacilli include enterobacteriaceae; pseudomonas, acinetobacteria and eikenella; melioidosis; salmonella; shigella; haemophilus; moraxella; H. ducreyi (causes chancroid); brucella species (brucellosis); Francisella tularensis (causes tularemia); Yersinia pestis (plague) and other Yersinia (pasteurella); Streptobacillus moniliformis and spirillum; Gram-positive bacilli include Listeria monocytogenes; Erysipelothrix rhusiopathiae; Corynebacterium diphtheria (causes diphtheria); cholera; Bacillus. anthracia (causes anthrax); donovanosis (granuloma inguinale; caused by Klebsiella granulomatis); and bartonellosis.

Pathogenic spirochetal diseases include syphilis; treponematoses: yaws, pinta and endemic syphilis; and leptospirosis. Other infections caused by higher pathogen bacteria and pathogenic fungi include glanders (Burkholderia mallei); actinomycosis; nocardiosis; cryptococcosis, blastomycosis, histoplasmosis and coccidioidomycosis; candidiasis, aspergillosis, and mucormycosis; sporotrichosis; paracoccidiodomycosis, petriellidiosis, torulopsosis, mycetoma and chromomycosis; and dermatophytosis. Rickettsial infections include Typhus fever; Rocky Mountain spotted fever; Q fever (Coxiella burnetti); and Rickettsialpox. Examples of mycoplasma and chlamydial infections include: Mycoplasma pneumoniae; lymphogranuloma venereum (caused by Chlamydia trachomatis); psittacosis; and perinatal chlamydial infections. Pathogenic eukaryotes encompassing pathogenic protozoans and helminths and infections produced thereby include: amebiasis (caused by Entamoeba histolytica); malaria (caused by Plasmodium); Leishmaniasis (caused by Leishmania); trypanosomiasis (caused by Trypanosoma); toxoplasmosis (caused by Toxoplasma gondii) Pneumocystis carinii; babesiosis (caused by Babesia); giardiasis (caused by Giardia lamblia); trichinosis (caused by roundworms of the genus Trichinella); filariasis (caused by roundworms of Filarioidea); schistosomiasis (carried by fresh water snails infected with one of the five varieties of the parasite Schistosoma); nematodes (Nematoda); trematodes or flukes (Platyhelminthes); and cestode (Cestoidea; tapeworm) infections.

Methods for Generating an AAV Virion

In various embodiments, the invention provides a method for generating an AAV virion of the invention. A variety of methods of generating AAV virions are known in the art and can be used to generate AAV virions comprising the AAV vectors described herein. Generally, the methods involve inserting or transducing an AAV vector of the invention into a host cell capable of packaging the AAV vector into and AAV virion. Exemplary methods are described and referenced below; however, any method known to one of skill in the art can be employed to generate the AAV virions of the invention.

An AAV vector comprising a heterologous nucleic acid and used to generate an AAV virion can be constructed using methods that are well known in the art. See, e.g., Koerber et al. (2009) Mol. Ther., 17:2088; Koerber et al. (2008) Mol Ther., 16: 1703-1709; as well as U.S. Pat. Nos. 7,439,065, 6,951,758, and 6,491,907. For example, the heterologous sequence(s) can be directly inserted into an AAV genome with the major AAV open reading frames (“ORFs”) excised therefrom. Other portions of the AAV genome can also be deleted, so long as a sufficient portion of the ITRs remain to allow for replication and packaging functions. Such constructs can be designed using techniques well known in the art. See, e.g., U.S. Pat. Nos. 5,173,414 and 5,139,941; International Publication Nos. WO 92/01070 (published Jan. 23, 1992) and WO 93/03769 (published Mar. 4, 1993); Lebkowski et al. (1988) Molec. Cell. Biol. 8:3988-3996; Vincent et al. (1990) Vaccines 90 (Cold Spring Harbor Laboratory Press); Carter, B. J. (1992) Current Opinion in Biotechnology 3:533-539; Muzyczka, N. (1992) Curr. Topics Microbiol. Immunol. 158:97-129; Kotin, R. M. (1994) Human Gene Therapy 5:793-801; Shelling and Smith (1994) Gene Therapy 1:165-169; and Zhou et al. (1994) J. Exp. Med. 179:1867-1875.

In order to produce AAV virions, an AAV vector is introduced into a suitable host cell using known techniques, such as by transfection. A number of transfection techniques are generally known in the art. See, e.g., Graham et al. (1973) Virology, 52:456, Sambrook et al. (1989) Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Laboratories, New York, Davis et al. (1986) Basic Methods in Molecular Biology, Elsevier, and Chu et al. (1981) Gene 13:197. Particularly suitable transfection methods include calcium phosphate co-precipitation (Graham et al. (1973) Virol. 52:456-467), direct micro-injection into cultured cells (Capecchi, M. R. (1980) Cell 22:479-488), electroporation (Shigekawa et al. (1988) BioTechnigues 6:742-751), liposome mediated gene transfer (Mannino et al. (1988) BioTechniques 6:682-690), lipid-mediated transduction (Feigner et al. (1987) Proc. Natl. Acad. Sci. USA 84:7413-7417), and nucleic acid delivery using high-velocity microprojectiles (Klein et al. (1987) Nature 327:70-73).

Suitable host cells for producing AAV virions include microorganisms, yeast cells, insect cells, and mammalian cells, that can be, or have been, used as recipients of a heterologous DNA molecule. The term includes the progeny of the original cell transfected. Thus, a “host cell” as used herein generally refers to a cell transfected with an exogenous DNA sequence. Cells from the stable human cell line, 293 (readily available through, e.g., the American Type Culture Collection under Accession Number ATCC CRL1573) can be used. For example, the human cell line 293 is a human embryonic kidney cell line that has been transformed with adenovirus type-5 DNA fragments (Graham et al. (1977) J. Gen. Virol. 36:59), and expresses the adenoviral Ela and Elb genes (Aiello et al. (1979) Virology 94:460). The 293 cell line is readily transfected, and provides a convenient platform in which to produce AAV virions.

Methods of producing an AAV virion in insect cells are known in the art, and can be used to produce a subject AAV virion. See, e.g., U.S. Patent Publication No. 2009/0203071; U.S. Pat. No. 7,271,002; and Chen (2008) Mol. Ther. 16:924.

In some embodiments, the AAV virion or AAV vector is packaged into an infectious virion or virus particle, by any of the methods described herein or known in the art.

In some embodiments, the AAV vector with the longer nucleic acid insert comprising the variant capsid polypeptide is packaged similarly to a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the AAV vector encoding the variant capsid polypeptide transduces cells in vivo similarly to a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the AAV vector encoding said variant capsid polypeptide is transduces cells in vitro similarly to a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the AAV vector encoding said variant capsid polypeptide results in transgene expression similarly to a vector encoding a non-variant parent capsid polypeptide and/or another variant capsid polypeptide.

In some embodiments, the AAV vector is wild type in length. In some embodiments, the variant capsid polypeptide that is more cationic than the non-variant parent capsid polypeptide and/or another variant capsid polypeptide allows for a larger portion of AAV virions that contain the AAV vector (i.e., that are packaged properly to contain the desired polynucleotide sequences) to be produced. In some embodiments, the variant capsid polypeptide that is more cationic than the non-variant parent capsid polypeptide and/or another variant capsid polypeptide allows for a reduction in the number of empty capsids produced. In some embodiments, the variant capsid polypeptide that is more cationic than the non-variant parent capsid polypeptide and/or another variant capsid polypeptide allows for a reduction of about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 80%, about 90% about 80%, about 90% or about 95% of empty capsids produced.

Method of Treating a Disease

The present invention also provides methods for treating a disease in a subject by administering the AAV vectors of the present invention. In an exemplary embodiment, the invention provides a method of administering a pharmaceutical composition of the invention to a subject in need thereof to treat a disease of a subject. In various embodiments, the subject is not otherwise in need of administration of a composition of the invention.

In some embodiments, the AAV virion or AAV vector comprises a therapeutic expression cassette comprises a heterologous nucleic acid comprising a nucleotide sequence encoding a heterologous gene product, such as for example a therapeutic protein

In some embodiments, the AAV virion or AAV vector is used in a therapeutic treatment regimen.

In some embodiments, the AAV virion or AAV vector is used for therapeutic polypeptide production.

In some cases, a subject AAV vector, when introduced into the cells of a subject provides for high level production of the heterologous gene product encoded by the AAV. For example, a heterologous polypeptide encoded by the AAV can be produced at a level of from about 1 μg to about 50 μg or more.

In some cases, a subject AAV virion or AAV vector, when introduced into a subject, provides for production of the heterologous gene product encoded by the AAV vector in at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 50% at least about 60%, at least about 70%, at least about 80%, or more than 80%, of the target cells.

In some embodiments, the present invention provides a method of treating a disease, the method comprising administering to an individual in need thereof an effective amount of a subject AAV virion as described above.

A subject AAV virion can be administered systemically, regionally or locally, or by any route, for example, by injection, infusion, orally (e.g., ingestion or inhalation), or topically (e.g., transdermally) Such delivery and administration include intravenously, intramuscularly, intraperitoneally, intradermally, subcutaneously, intracavity, intracranially, transdermally (topical), parenterally, e.g. transmucosally or rectally. Exemplary administration and delivery routes include intravenous (i.v.), intraperitoneal (i.p.), intrarterial, intramuscular, parenteral, subcutaneous, intra-pleural, topical, dermal, intradermal, transdermal, parenterally, e.g. transmucosal, intra-cranial, intra-spinal, oral (alimentary), mucosal, respiration, intranasal, intubation, intrapulmonary, intrapulmonary instillation, buccal, sublingual, intravascular, intrathecal, intracavity, iontophoretic, intraocular, ophthalmic, optical, intraglandular, intraorgan, and intralymphatic.

In some cases, a therapeutically effective amount of a subject AAV virion is an amount that, when administered to an individual in one or more doses, is effective to slow the progression of the disease or disorder in the individual, or is effective to ameliorate symptoms. For example, a therapeutically effective amount of a subject AAV virion can be an amount that, when administered to an individual in one or more doses, is effective to slow the progression of the disease by at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, or more than about 80%, compared to the progression of the disease in the absence of treatment with the AAV virion.

A therapeutic or beneficial effect of treatment is therefore any objective or subjective measurable or detectable improvement or benefit provided to a particular subject. A therapeutic or beneficial effect can but need not be complete ablation of all or any particular adverse symptom, disorder, illness, or complication of a disease. Thus, a satisfactory clinical endpoint is achieved when there is an incremental improvement or a partial reduction in an adverse symptom, disorder, illness, or complication caused by or associated with a disease, or an inhibition, decrease, reduction, suppression, prevention, limit or control of worsening or progression of one or more adverse symptoms, disorders, illnesses, or complications caused by or associated with the disease, over a short or long duration (hours, days, weeks, months, etc.).

Improvement of clinical symptoms can also be monitored by one or more methods known to the art, and used as an indication of therapeutic effectiveness. Clinical symptoms may also be monitored by anatomical or physiological means, such as indirect ophthalmoscopy, fundus photography, fluorescein angiopathy, optical coherence tomography, electroretinography (full-field, multifocal, or other), external eye examination, slit lamp biomicroscopy, applanation tonometry, pachymetry, autorefaction, or other measures of functional vision. In some embodiments, a subject AAV virion or virus, when introduced into a subject, provides for production of the heterologous gene product encoded by the AAV for a period of time of from about 2 days to about 6 months, e.g., from about 2 days to about 7 days, from about 1 week to about 4 weeks, from about 1 month to about 2 months, or from about 2 months to about 6 months. In some embodiments, an AAV virion or virus, when introduced into a subject provides for production of the heterologous gene product encoded by the AAV for a period of time of more than 6 months, e.g., from about 6 months to 20 years or more, or greater than 1 year, e.g., from about 6 months to about 1 year, from about 1 year to about 2 years, from about 2 years to about 5 years, from about 5 years to about 10 years, from about 10 years to about 15 years, from about 15 years to about 20 years, or more than 20 years.

Multiple doses of a subject AAV virion can be administered to an individual in need thereof. Where multiple doses are administered over a period of time, an active agent is administered once a month to about once a year, from about once a year to once every 2 years, from about once every 2 years to once every 5 years, or from about once every 5 years to about once every 10 years, over a period of time. For example, a subject AAV virion is administered over a period of from about 3 months to about 2 years, from about 2 years to about 5 years, from about 5 years to about 10 years, from about 10 years to about 20 years, or more than 20 years. The actual frequency of administration, and the actual duration of treatment, depends on various factors.

The dose to achieve a therapeutic effect, e.g., the dose in vector genomes/per kilogram of body weight (vg/kg), will vary based on several factors including, but not limited to: route of administration, the level of heterologous polynucleotide expression required to achieve a therapeutic effect, the specific disease treated, any host immune response to the viral vector, a host immune response to the heterologous polynucleotide or expression product (protein), and the stability of the protein expressed. One skilled in the art can readily determine a virion dose range to treat a patient having a particular disease or disorder based on the aforementioned factors, as well as other factors. Generally, doses will range from at least about, or more, for example, about 1×10⁹, 1×10 ¹⁰, 1×10 ¹¹, 1×10 ¹², 1×10 ¹³ or 1×10¹⁴, or more, vector genomes per kilogram (vg/kg) of the weight of the subject, to achieve a therapeutic effect.

An effective amount or a sufficient amount can but need not be provided in a single administration, may require multiple administrations, and, can but need not be, administered alone or in combination with another composition (e.g., agent), treatment, protocol or therapeutic regimen. For example, the amount may be proportionally increased as indicated by the need of the subject, type, status and severity of the disease treated or side effects (if any) of treatment. In addition, an effective amount or a sufficient amount need not be effective or sufficient if given in single or multiple doses without a second composition (e.g., another drug or agent), treatment, protocol or therapeutic regimen, since additional doses, amounts or duration above and beyond such doses, or additional compositions (e.g., drugs or agents), treatments, protocols or therapeutic regimens may be included in order to be considered effective or sufficient in a given subject. Amounts considered effective also include amounts that result in a reduction of the use of another treatment, therapeutic regimen or protocol, such as administration of recombinant clotting factor protein for treatment of a clotting disorder (e.g., hemophilia A or B).

An effective amount or a sufficient amount need not be effective in each and every subject treated, or a majority of treated subjects in a given group or population. An effective amount or a sufficient amount means effectiveness or sufficiency in a particular subject, not a group or the general population. As is typical for such methods, some subjects will exhibit a greater response, or less or no response to a given treatment method or use. Thus, appropriate amounts will depend upon the condition treated, the therapeutic effect desired, as well as the individual subject (e.g., the bioavailability within the subject, gender, age, etc.).

With regard to a disease or symptom thereof, or an underlying cellular response, a detectable or measurable improvement includes a subjective or objective decrease, reduction, inhibition, suppression, limit or control in the occurrence, frequency, severity, progression, or duration of the disease, or complication caused by or associated with the disease, or an improvement in a symptom or an underlying cause or a consequence of the disease, or a reversal of the disease.

Thus, a successful treatment outcome can lead to a “therapeutic effect,” or “benefit” of decreasing, reducing, inhibiting, suppressing, limiting, controlling or preventing the occurrence, frequency, severity, progression, or duration of a disease, or one or more adverse symptoms or underlying causes or consequences of the disease in a subject. Treatment methods and uses affecting one or more underlying causes of the disease or adverse symptoms are therefore considered to be beneficial. A decrease or reduction in worsening, such as stabilizing the disease, or an adverse symptom thereof, is also a successful treatment outcome.

A therapeutic benefit or improvement therefore need not be complete ablation of the disease, or any one, most or all adverse symptoms, complications, consequences or underlying causes associated with the disease. Thus, a satisfactory endpoint is achieved when there is an incremental improvement in a subject's disease, or a partial decrease, reduction, inhibition, suppression, limit, control or prevention in the occurrence, frequency, severity, progression, or duration, or inhibition or reversal, of the disease (e.g., stabilizing one or more symptoms or complications), over a short or long duration of time (hours, days, weeks, months, etc.). Effectiveness of a method or use, such as a treatment that provides a potential therapeutic benefit or improvement of a disease, can be ascertained by various methods.

Disclosed methods and uses can be combined with any compound, agent, drug, treatment or other therapeutic regimen or protocol having a desired therapeutic, beneficial, additive, synergistic or complementary activity or effect. Exemplary combination compositions and treatments include second actives, such as, biologics (proteins), agents and drugs. Such biologics (proteins), agents, drugs, treatments and therapies can be administered or performed prior to, substantially contemporaneously with or following any other method or use of the invention, for example, a therapeutic method of treating a subject for a blood clotting disease.

The compound, agent, drug, treatment or other therapeutic regimen or protocol can be administered as a combination composition, or administered separately, such as concurrently or in series or sequentially (prior to or following) delivery or administration of an AAV vector or AAV virion as described herein. The invention therefore provides combinations where a method or use of the invention is in a combination with any compound, agent, drug, therapeutic regimen, treatment protocol, process, remedy or composition, set forth herein or known to one of skill in the art. The compound, agent, drug, therapeutic regimen, treatment protocol, process, remedy or composition can be administered or performed prior to, substantially contemporaneously with or following administration of an AAV vector or AAV virion as described herein, to a subject. Specific non-limiting examples of combination embodiments therefore include the foregoing or other compound, agent, drug, therapeutic regimen, treatment protocol, process, remedy or composition.

Methods and uses of the invention also include, among other things, methods and uses that result in a reduced need or use of another compound, agent, drug, therapeutic regimen, treatment protocol, process, or remedy. For example, for a blood clotting disease, a method or use of the invention has a therapeutic benefit if in a given subject a less frequent or reduced dose or elimination of administration of a recombinant clotting factor protein to supplement for the deficient or defective (abnormal or mutant) endogenous clotting factor in the subject. Thus, in accordance with the invention, methods and uses of reducing need or use of another treatment or therapy are provided.

The invention is useful in animals including veterinary medical applications. Suitable subjects therefore include mammals, such as humans, as well as non-human mammals. The term “subject” refers to an animal, typically a mammal, such as humans, non-human primates (apes, gibbons, gorillas, chimpanzees, orangutans, macaques), a domestic animal (dogs and cats), a farm animal (poultry such as chickens and ducks, horses, cows, goats, sheep, pigs), and experimental animals (mouse, rat, rabbit, guinea pig). Human subjects include fetal, neonatal, infant, juvenile and adult subjects. Subjects include animal disease models, for example, mouse and other animal models of blood clotting diseases and others known to those of skill in the art.

Non-limiting particular examples of diseases treatable in accordance with the invention include those set forth herein as well as a lung disease (e.g., cystic fibrosis), a blood coagulation or bleeding disorder (e.g., hemophilia A or hemophilia B with or without inhibitors), thalassemia, a blood disorder (e.g., anemia), Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis (ALS), epilepsy, lysosomal storage diseases, a copper or iron accumulation disorders (e.g., Wilson's or Menkes disease) lysosomal acid lipase deficiency, a neurological or neurodegenerative disorder, cancer, type 1 or type 2 diabetes, Gaucher's disease, Hurler's disease, adenosine deaminase deficiency, a metabolic defect (e.g., glycogen storage diseases), a retinal degenerative disease (such as RPE65 deficiency or defect, choroideremia, and other diseases of the eye), and a disease of a solid organ (e.g., brain, liver, kidney, heart).

In one embodiment, a method or use of the invention includes: (a) providing an AAV virion prepared as described herein, comprising a heterologous nucleic acid sequence, wherein the heterologous polynucleotide sequence is operably linked to an expression control element conferring transcription of said polynucleotide sequence; and (b) administering an amount of the AAV virion to the mammal such that said heterologous polynucleotide is expressed in the mammal.

In another embodiment, a method or use of the invention includes delivering or transferring a heterologous polynucleotide sequence into a mammal or a cell of a mammal, by administering an AAV virion prepared as described herein, or a plurality of AAV virions comprising the heterologous nucleic acid sequence to a mammal or a cell of a mammal, thereby delivering or transferring the heterologous polynucleotide sequence into the mammal or cell of the mammal. In some embodiments, the heterologous nucleic acid sequence encodes a protein expressed in the mammal, or where the heterologous nucleic acid sequence encodes an inhibitory sequence or protein that reduces expression of an endogenous protein in the mammal.

By way of example, respecting hemophilia, it is believed that, in order to achieve a therapeutic effect, a blood coagulation factor concentration that is greater than 1% of factor concentration found in a normal individual is needed to change a severe disease phenotype to a moderate one. A severe phenotype is characterized by joint damage and life-threatening bleeds. To convert a moderate disease phenotype into a mild one, it is believed that a blood coagulation factor concentration greater than about 5% of normal is needed. With respect to treating such a hemophilic subject, a typical dose is at least 1×10¹⁰ AAV vector genomes (vg) per kilogram (vg/kg) of the weight of the subject, or between about 1×10¹⁰ to about 1×10¹¹ vg/kg of the weight of the subject, or between about 1×10¹¹ to about 1×10¹² vg/kg of the weight of the subject, or between about 1×10¹² to about 1×10¹³ vg/kg of the weight of the subject, to achieve a desired therapeutic effect.

Ocular diseases that can be treated or prevented using a subject method include, but are not limited to, selected from acute macular neuroretinopathy; macular telangiectasia; Behcet's disease; choroidal neovascularization; diabetic uveitis; histoplasmosis; macular degeneration, such as acute macular degeneration, Scorsby's macular dystrophy, early or intermediate (dry) macular degeneration, or a form of advanced macular degeneration, such as exudative macular degeneration or geographic atrophy; edema, such as macular edema, cystoid macular edema and diabetic macular edema; multifocal choroiditis; ocular trauma affecting a posterior ocular site or location; ocular tumors; retinal disorders, such as central retinal vein occlusion, diabetic retinopathy (including proliferative and non-proliferative diabetic retinopathy), proliferative vitreoretinopathy (PVR), retinal arterial occlusive disease, retinal detachment, uveitic retinal disease; sympathetic opthalmia; Vogt Koyanagi-Harada (VKH) syndrome; uveal diffusion; a posterior ocular condition caused by or influenced by an ocular laser treatment; posterior ocular conditions caused by or influenced by a photodynamic therapy, photocoagulation, radiation retinopathy; epiretinal membrane disorders; central or branch retinal vein occlusion; anterior ischemic optic neuropathy, non-retinopathy diabetic retinal dysfunction; retinitis pigmentosa; retinoschisis; and glaucoma.

EXAMPLES Example 1 AAV Vectors with Expanded Packaging Capacity Purpose:

The goal of the study is to derive AAV vectors that have expanded carrying capacity. One of the limitations of existing vectors is that the amount of exogenous DNA that can be packaged is limited. Being able to package longer inserts would be valuable to the gene therapy community.

Technical Description (Abstract):

It was reasoned that AAV vectors that had a capsid protein composition with a higher positive (cationic) charge in key regions would possibly allow for increased packaging capacity. The idea is based on the fact that DNA is negatively charged and if placed into the appropriate region would allow for more DNA-- perhaps because it would be packaged in a more compact manner. Regardless of mechanism, we made AAV capsid variants that contained various amino acid substitutions that would make the capsid more anionic or cationic. It has been found that several of the cationic variants packaged larger DNA inserts. To date, it has been demonstrated the new capsids can package at least 5.4 Kb. Control standard vectors package up to 4.8 kb. So to date we have expanded the capacity by at least 600 nucleotides.

Applications:

The AAV vectors described herein can package: 1) Longer coding sequences (e.g. hFVIII) 2) Longer expression cassettes 3) Longer multi-expression cassettes 4) Longer sequences for homologous recombination

Usefulness:

The AAV vectors described herein find usefulness in 1) all gene therapy companies 2) companies interested in genome engineering with or without nucleases 3) Expressed RNAi companies 4) Stem cell companies that genetically modify their cells

Advantages:

1) There are several types of applications where packaging into AAV does not fit. Factor VIII is one example where there is marginal or suboptimal packaging. With our new capsid we should be able to package well established expression cassettes 2) CRISPR/CAS systems -- complete systems could be better delivered in a single AAV

Variations:

1) Additional cationic amino acid substitutions may enhance packaging and 2) Modifying the capsid sequence of currently existing capsids could result in expanding packaging capacity of any AAV vector serotype.

Although there have been claims of AAV vectors (mostly naturally existing serotypes) that have expanded packaging capacity-- the results have not been replicated. AAV variant capsids with expanded packaging as described herein present a novel addition to the field.
